Roundslings
 
Description
Roundsling consists of a load bearing core of yarn, completely enclosed in a woven cover, with or without fittings for attaching loads to the hook of a crane or other lifting machine, and it is intended for general purpose lifting operations, i.e. when used for lifting objects, materials or goods, but not including the lifting of persons, potentially dangerous materials such as molten metal and acids, glass sheets, fissile materials, nuclear reactors and where special conditions apply. The components of core and woven cover are made of polyamide, polyester or polypropylene industrial multifilament. It becomes a very cost effective lifting sling that is soft to touch and much less likely to cause damage the material being lifted; it will not cause the type of injuries to the user, compared to lifting with wire rope sling, say, cuts caused by broken wires, manual handling or impact injuries. Round lifting slings are compact and light weight than both wire rope or chain slings and as a result, they are much easier to handle. Fibre round slings are comparitively cheap compared to most alternative lifting slings and tend to be more flexible, lighter and money saving.On the negative side endless slings do have less abrasive resistance though this can be overcome by using a wear sleeve made from either polyester or from polyurethane. Other alternative method to provide sling protection would be to use steel end fitting such as Grade 80/100 master rings and sling hooks; or the use or corner protectors.All slings are colour coded, identifying the relevant working load limit, and are individually labelled stating sling number, material, length, date of manufacture and any relevant safety information
 
 
Technical parameter
Material: 100% polyester (PES), high tenacity multifilament
          100% polyamide (PA), high tenacity multifilament
100% polypropylene (PP), high tenacity multifilament
Performed standard: EN1492-2:2000, JB/T8521.2-2007, AS4497.1-1997
Safety factor: 7:1, 6:1, 8:1, 5:1
Length: Available from 1 to 80m or as required
Width: 40mm to 670mm inclusive
WLL: 1.00 to 400.00 ton inclusive

Endless polyester roundsling
Made from 100% high tenacity polyester (PES),to EN1492-2, single and double-layer roundsling sleeves optional, attached with capacity label.

Features:
For its endless shape, the using life to be added by change of the load bearing point;
Handling easily and tight adhesion to the surface of load;
High force to weight ratio;
Color code, in light of international standard to validate sling capacity;
Each stripe equals to 1 ton capacity, which sling capacity is discerned easily;
Light and supple;
No damage to delicate and painted surfaces;
Polyester roundsling is resistant to most mineral acids but damaged by alkalis (Polyamide roundsling is virtually immune to the effect of alkalis but attacked by mineral acids. Polypropylene roundsling is little affected by acids or alkalis and suitable for use where the highest resistance to chemicals other than solvents is required). Immune to complete water, oil and grease;
Utilisations without gloves or other protections.
Low extension not more than 3% at rated capacity.
Work and storage temperature range is -40¡æ to 100¡æ (-40¨H to 212¨H), which is identical to that
of roundsling made from nylon but different
from -40¡æ to 80¡æ (-40¨H to 176¨H) of the roundsling made from polypropylene.
High resistance to abrasion;
No junctions inside.
